In 2002 Tim Sheldon gives $10,000 to a Republican campaign committee that tosses the state senate to the GOP.
In 2004 he votes for and supports the Republican candidate for governor.
In 2004 he heads up the local chapter of Democrats for Bush.
This year he fails to get the endorsement of any local Democratic Party organization.
He is listed by the Republican senate campaign committee as a Republican.
In 2006 he receives $500 from a Republican PAC, $100 more than is even raised by his Republican opponent.
Now, he endorses the Republican opponent of a Democratic representative from his own district.
So, I ask you, why do parties matter at all?
