Wisconsin Gov. Scott Walker announced Monday evening he's dropping out of the race for the White House.
Walker said he's suspending his campaign so that voters can focus on a more limited number of Republican candidates from which to choose.
Walker spoke for less than five minutes and did not answer any questions. His announcement comes after a very poor showing in the latest GOP presidential polls.
Walker essentially got 0 percent support when respondents were asked who they were most likely to support for the GOP nomination, according to a CNN/ORC International poll released Sunday.
Instead, he simply got an asterisk – which means below 1 percent. In late July he was at 10 percent – third behind Donald Trump and Jeb Bush. Walker's support has continually dropped since.
Walker's performance in the second GOP debate last week wasn't strong enough to generate any excitement about his candidacy, and that caused concerns about his ability to attract enough funding to keep his campaign going, the Milwaukee Journal Sentinel reports.
The Associated Press reported following last week's debate that Walker's campaign had more than $100,000 in outstanding debts, and staffers had tried to convince donors that Walker was still a viable candidate.
Although Walker has a super PAC that's reportedly raised $20 million, that money cannot directly pay for his campaign expenses.
One of the biggest donors to Walker's super PAC is Minnesota media mogul Stanley Hubbard, who has given $50,000, according to The Hill. Hubbard says he is considering throwing his support behind one of several of the other candidates.
GOP media strategist Liz Mair, who worked for Walker's gubernatorial campaigns, sent out

(Note: Mair was forced off the Walker campaign in March for Twitter comments that criticized Iowa and its caucuses.)
The Associated Press notes Walker wasn't able to adjust to the popularity of Donald Trump, and he stumbled on several occasions trying to articulate his positions on various issues.
His public comments on birthright citizenship and the value of building a wall between the U.S and Canada to deter illegal immigrants changed over the course of several days, according to the Associated Press.
He also declared he wasn't a career politician, even though he has held public office for 22 years. His current term as governor of Wisconsin ends in 2018.
Walker's departure still leaves 15 other candidates in the GOP race. Texas Gov. Rick Perry dropped out earlier this month.
