I'm not sure whether people like Ryan and Priebus would risk this to get Trump elected. There probably were contacts between shady people in Trump's campaign and Russia, but I really don't think your average Republican establishment guy would collude with Russia to get Trump elected. These people don't care about Trump. A lot of them probably even wanted Trump to lose so that their favoured candidate could win 2020. A Trump loss would have meant a lame duck Democratic president who wouldn't have gotten anything done, a huge senate majority in 2018 and possibly a trifecta with huge majorities and a more establishment-friendly president in 2020. But Flynn definitely is in trouble.
They were willing to ride a racist sex predator as far as he'd take them, so I doubt this would give them pause tbh. Aside from the occasional Ben Sasse or John Kasich, most Republican elected officials sold their souls to Trump long before he was elected.
