In Missouri, Rep. Ann Wagner is planning to enter the Senate race in July, according to two sources familiar with her plans, and has seen private polling showing her already leading Sen. Claire McCaskill. Officials from both parties agree that McCaskill is the most vulnerable Democrat up for re-election.

The second worst-kept secret of the 2018 cycle, right behind Scott Walker’s obvious intentions to run again, is Wagner’s Senatorial ambitions. Josh Kraushaar reports the run is a go with a Summer announcement. Wagner has amassed a considerable war chest of nearly $2.7 million for this rather obvious gambit, and incumbent Senator Claire McCaskill has been fundraising like mad this year as Democrats have reacted strongly to President Donald Trump, sporting over $2.8 million cash on hand. We at the Desk have McCaskill as the most vulnerable Democratic incumbent up next year, mainly for reasons Kraushaar explores in that article: GOP Senatorial recruitment has been terribly uneven, while on the House side Democrats are amped up everywhere.
