In the summer of 2007, as he was contemplating a run for state-wide office in a year that will likely bring big wins for Democrats across the board, Republican Chris Koster, on the turn of a dime, announced he was no longer a Republican. After years of spearheading Republican initiatives and towing the Republican party line in the Missouri Legislature, Koster decided to cross the aisle.

Koster wants you to believe this was a principled decision, but once you look at the facts, it’s clear this was a decision of political expediency.

A decision to further his own ambitions.

A decision based not on what’s best for Missouri, but based on what’s best for Chris Koster.

A decision he clearly has no plans to stick with once he gets what he wants.

You need to look no further than Koster’s biggest fundraiser – right-wing multi-millionaire Rex Sinquefield, who as we speak, is helping Koster circumvent campaign finance laws – to understand the truth about Koster the Imposter.
