The terms used for votes in the United States are as follows:

Bipartisan – support from more than one party. (It can also mean opposition from more than one party, but it customarily is phrased “bipartisan opposition”. Without the clarifier, it is implied to mean support.)

Party Line – when all the members of one party support a bill and all the members of another oppose it.

Incidentally, it is in the best interest of the gay community that pro-gay votes be bipartisan. Independents – who make up about a third of the populace – tend to favor bipartisan votes but are much less favorable to partisan ones, irrespective of the issue or result. Which is why you will see every gay group trumpet the fact that this was a bipartisan vote.

It is, of course, not in the best interest of the the political parties when votes are bipartisan. Sharp divisions improve contributions and fuel campaigns.

So I guess you need to figure out which is more important to you.

(If it helps, while anti-gay extremists HATE bipartisan votes, most Democratic politicians seem to be delighted with the bipartisan nature of pro-gay votes. Even politicians sometimes put supporting what’s right ahead of their own partisan interests.)

Quite sad.
