Could you draw a 5-2 in CO or would a 4-3 be safer?
4-3 would probably be safer, though I think 5-2 isn’t impossible. However, noting the unfortunate Californication of the state, we’d probably have to shoot for the former. For a brief time in the ‘90s, had the GOP a free hand, they could’ve gotten a 5-1 delegation (as Boulder’s 2nd became briefly marginal — hell, even the 1st reached the point that the late Joe Rogers scared Patsy Schroeder into retirement).
5-2 would be safe enough if one is creative, such as connecting heavily RAT parts of Pueblo to Boulder through rural Hispanic counties and liberal ski counties.
