"French Rassemblement National (National Rally) leader Marine Le Pen has been possibly one of the most vocal supporters of the Yellow Vests, of course, condemning any violence seen on the Champs Elysees saying: “Of course we condemn the violence. But often, this violence emanate from the same: the black blocs, the “Antifa” groups. The most serious violence comes from these extreme leftist groups.”LePen (on the left in the picture with Salvini of Italy on the right) 
LePen gave Macaroni a good run in the last election and is leading the Limousine Liberal Globalist at the moment.
France, BVA poll:
Approval ratings (president+party leaders)
Le Pen (RN-ENF): 27% (+3)
Macron (LREM-ALDE): 26% (-3)
Dupont-Aignan (DLF-EFDD): 25%
Ruffin (PD-*): 23%
Besancenot (NPA-LEFT): 22% (+1)
Hamon (G.s.-S&D: 21% (-2)
Field work: 21/11/18 – 22/11/18
And that above from Breitbart is old news. Some polls in recent days are showing Macron at 20-23% approval.

The anarchists are out every day but the vast majority of the protestors are out on the weekends for a very logical reason: they are working class people, largely non-violent and they are working during the week.
Marine Le Pen is not an American style free market, regulation cutting, limited government conservative. She is more in the line of a traditional French nationalist in opposition, with anti-tax, Euroskeptic, and anti-Islam sentiments that reflect current popular concerns. What would Le Pen do though if she attained power on her terms?
In addition to securing the French Presidency, Le Pen also aims to establish her National Front as a viable new political party and a vehicle for the views of its marginalized adherents. Yet, even with such political power in hand, Le Pen does not seem to intend a drain-the-swamp housecleaning or major institutional changes in France's system of government. I suggest that this reflects not so much any weakness in Le Pen but larger political circumstances that hinder the Right in Europe.
Notably, Le Pen, Salvini, and other West European political leaders on the Right lack the intellectual and organizational support such as supports and energizes American conservatives. Indeed, contemporary Europe offers little political space to conservatism. The Left dominated the anti-Nazi Resistance movements and then was cemented into power after WW II. They relentlessly smeared opposing ideas and personalities on the Right as tainted by fascism and Nazi ideology.
This well-established and highly effective line of attack is virtually a political reflex and is relied on to discredit the Right in Europe and hinder its political development. The continent's various anti-Leftist political movements thus struggle to articulate political principles that transcend their national experience and circumstances so as to provide a coherent vision and core ideas on the Right as a basis for mutual support and common political goals.
As for the current French riots, they manifest popular discontent but seem unlikely to result in a revolution of any sort, whether on the streets or at the ballot box. In time though, the growing Muslim population and the looming bankruptcy of the welfare state seem likely to result in a breakdown of the French state and a low-intensity civil war in France.
A generation or two from now, France may be more an expression of geography than a functioning, unified nation-state. The French populace may be divided into separate Muslim and Christian cantonments with limited common urban commercial zones. Or, the cruel logic of Islam may prompt the kind of genocide tinged population displacements common to the history of the Muslim world and thus result in a more or less unitary French nation.
Against the menace and harshness of such a future, just what does American style conservatism have to offer France? It may be that behind the scenes, Europe is preparing for an era in which the ideologies of the Enlightenment are mostly irrelevant.
