Today's installment of campaign-related news items that won't necessarily generate a post of their own, but may be of interest to political observers:
* In advance of the June 24 runoff election in Mississippi's Republican U.S. Senate race, some of incumbent Thad Cochran's allies have walked away, but the Club for Growth is launching a new TV ad today in support of Chris McDaniel.
* A new Bloomberg poll shows Democrats and Republicans tied on the generic congressional ballot, 39% to 39%. Add in voters leaning one way of the other and it's 43% to 43%.
* Alaska Republicans have not yet chosen their U.S. Senate candidate, but the frontrunner, Dan Sullivan, challenged Sen. Mark Begich (D) yesterday to agree that both sides will disavow all support from outside groups. Begich didn't accept, instead asking why Sullivan, who's benefited greatly from outside support, hasn't opposed the Citizens United ruling.
* A new Republican poll in Kentucky shows Allison Lundergran Grimes (D) leading Senate Minority Leader Mitch McConnell (R) by three, 49% to 46%.
* Maine held a Republican primary this week, but according to the state's Democratic Party, Gov. Paul LePage (R) didn't bother to participate in it.
* In Illinois, a new statewide poll shows Bruce Rauner (R) with a 10-point advantage over incumbent Gov. Pat Quinn (D), 47% to 37%.
* And a group called the Asian Republican Coalition hopes to improve the GOP's performance with Asian-American voters, who've become sharply more Democratic in recent election cycles. The Asian Republican Coalition, however, apparently believes it can help by adopting a "very broad definition of what constitutes the Asian American community" -- and their definition includes people who've lived or done business in Asian countries.
