Will Dave Reichert get Koch blocked?

Today in As the Republicans Turn on Each Other: A Koch-funded group, Americans for Limited Government, slams Washington State Republican Congressman Dave Reichert via the following press release:

When it counted, Rep. Reichert was nowhere to be found in the fight to defund Obamacare. Just three weeks after taking a symbolic vote in favor of defunding, when it finally mattered Reichert turned around and voted to allow funding for the implementation of Obamacare to take effect. By voting to fund it, Reichert now owns Obamacare just as much as if it had been a vote to adopt it in the first place. There is no running away from that fact.

No running! Is this a signal that Reichert will have a Tea Party challenger when he's up for election next year.
