The early results do not look good with most of the networks showing 3 key Indiana seats (2nd, 8th and 9th) swinging to the GOP but Kentucky 6th is leaning to the Democrats and that could show it’s not a complete blowout.
Over at 538.com the projections are up to the mid to upper 50 seat gain for the GOP which would be a bad outcome for the GOP. Nate is liberal but generally fair in his analysis, though if it was tilted any direction it would be for the Dems, so a mid 50’s loss is bad news for them.
