Why was the thread about who you're voting for in the United States Congress deleted?

The thread and the poll were active during the 2008 presidential elections and the 2010 midterms too. Now they're gone, and when I tried to recreate them, they were wiped without a single word of explanation. Why...

Maybe it's just because... it's election day silence?

I don't get that argument at all. During the presidential and congressional elections, people voted for their candidates without any issues, just like they vote freely in polls. This is ridiculous; my posts aren't propaganda, especially since the media is running exit polls right this second.

If what you're saying is actually true, then is the issue just when I start a thread? Is it suddenly a crime if I post after midnight?...
