Democrats interested in the Presidential race should be happy. Winning Latino and Asian voters just got easier. For Democrats who were praying for the miracle that immigration reform would somehow pass the House during this Congress, their hopes have been dashed.
...or the next Congress. Or the next. Or even the one after that. Cantor's loss will seriously discourage bipartisan discussion on the issue and could derail such reform. For the rest of the decade.
That's fine. The only way anything ever gets done is when there is a Democratic House, Democratic President, and 60 Democratic Senators. Cantor's absence or presence isn't going to change that, but another Tea Party loon in Congress makes the march to supermajority easier.
