McKeon is seen, at least by Democrats, as one of the old guard who could be on the way out this cycle.
Take, for example, Rep. Michael M. Honda, who faces a stiff challenge from another Democrat. With a top team and massive war chest, attorney Ro Khanna is every incumbentís nightmare, and heíll likely battle Honda through Election Day 2014.
Similarly, Rep. Henry A. Waxman, D-Calif,, cruised to re-election for decades with more than 60 percent of the vote ó until last year. The 74-year-old faced the biggest House self-funder of the cycle, independent Bill Bloomfield.
Waxman survived last cycle, but Hondaís fate for 2014 is unclear. If he goes down, other incumbents will have to look at his predicament and wonder whether they will be next. If so, will going through with a campaign like that be worth it?
