They can’t stop a write-in campaign.
Write in Brat.
This election Tuesday is “it”, no write-in needed .... Cantor vs Brat. Whoever wins is the Repub on the ballot in November and there is no Dem challenger. If Cantor loses, he’s out of DC. If Brat wins, he’s in. The stakes are high so Cantor is throwing everything but the kitchen sink at this one .... and odds are he’ll likely pull it off.
