Yes, although as some others pointing out in comments, the DNC is not doing well with fundraising. The RNC meanwhile is having record fundraising, and would be using that to fund GOTV, which ought to be even better with all of the new data from the 2016 election cycle than it was then...perhaps that can offset any fundraising advantages by individual Dem candidates.
And if poll numbers continue to improve for President Trump and the GOP, the donors may end up changing their minds who to give the cash to as the cycle goes on.
Big donor Democrats are expressing unhappiness with the DNC, but supporting individual candidates. It has been noted for some time that big Dem Jewish donors have been shifting their donations into PACs instead of the FNC.
PACs allow more control to the donors.
Big donor Republicans are rewarding the RNC for their lukewarm support for, or even hostility to, Pres. Trump.
