Correction: Heinrich led by 7 percentage points in an internal campaign poll released last week. A previous version of this story misstated his lead.
Former Rep. Heather Wilson, R-N.M., left the House of Representatives in early 2009, but you wouldn't know that by watching Democratic Rep. Martin Heinrich's latest television ad.
"Heather Wilson has been in Washington a long time," the narrator of the ad says. "After ten years in Congress, she's lost touch with New Mexico families."
Of course, Heinrich is well aware that Wilson no longer serves in Congress: he succeeded her in 2009 as the representative from New Mexico's 1st Congressional District. The two are now facing off in one of the most highly-watched Senate races of the cycle.
Heinrich also has been targeted for his congressional service, with Wilson attacking his "Washington spending" in her latest TV spot. Heinrich's first negative ad of the campaign is an attempt to turn the issue around on Wilson and paint the Republican as the incumbent in the race.
Considered a slight favorite, Heinrich released an internal poll last week that showed him leading Wilson by 7 percentage points.
