I mentioned this to two of my colleagues and they told me they already had! One of them grew up in a red state and said that’s the only way she’s been able to affect politics– through primaries. The other said he did it after the presidential election.
It seems messed up, but our local Indivisible group has said that their goal is not to run a dem but to find a moderate republican with morals to primary our tea party congressman. I agree that’s a good goal given our current district stats, as much as I miss the blue-dog dem we had before he was gerrymandered out of existance.
I will still, of course, vote straight blue ticket in the main election, so I hope the dems find someone to run.
