the 2 dem congressional campaign committees (dccc/dlcc) have outraised their gop counterparts (nrcc/nrsc) by over $30 mil combined. the dem governors association is outraising the gop one handily too.

even beto orourke outraised tea party darling ted cruz last quarter...while accepting zero pac money.

repubs cant even field any quality challengers to vulnerable dem senators in a lot of states that trump won like ohio, north dakota, tennessee, etc. even claire mccaskell...who was thought to be vulnerable...is outraising her next best challenger by like a 2:1 margin. repubs are even begging corker not to retire now so they wont lose the senate seat in tennessee.

the amount of republicans in congress retiring or not seeking re-election is already at a record number, including 9 committee chairmen! (which means they dont expect to be in the majority next year). even trey gowdy is headed for the hills.

repubs are getting beat up and down the ballot at every level of government by wide swing margins in elections dating back through last year. and they have to spend like crazy and bring in outside help just to hold on to safe red seats they have held for decades.

repub party identification is down almost 10% since right before the 2016 election. and women are leaving the party at an alarming rate...creating an overall trump approval gender gap of around 20pts (obama was around 6).

those are *tangible* indicators of the current environment and what even repubs expect to happen in november.

aside from media narrative and poll numbers...where are you seeing signs of this momentum for republicans?
