Mimes. They need more mimes.
Yep. And more of those giant European street puppets. No street puppets, low Marple index. Low Marple index, lost election.
It's a little vague what "A" Tea Party means, but if it means similar to the grassroots movements (plural) unified not by program but by love of country, then no, because the signal characteristic of all the groups marching in opposition to Trump's inauguration was hatred of their country. They were able to focus that on Trump due to the occasion but it is not otherwise a unifying characteristic.
If a dose of populism is what "A" Tea Party means, then perhaps, but that wasn't the crowd we saw last weekend. The swing of the Democrat party away from populism cost them the working class vote, and the election. The swing toward establishmentarian statism and authoritarianism cost them the populist vote even within their party - ask any of the Sanders crowd, particularly the ones who ended up voting for Trump out of pure disgust.
What the Tea Party movement lacked was validation in the media; to be more accurate, what it received was mockery and inveterate hostility. That's a tough gradient to pull against. But the media, and here I include that ridiculous gaggle of pompous Hollywood celebrities, the media are now Establishment, the price of selling out to power. That's going to make any populist movement pull against that same gradient, as Sanders found out. The closest the Dems are likely to come to the Tea Party movement was murdered in the womb when Hillary and the Dem establishment put the skids under Bernie, and that's going to haunt them.
