On Tuesday, Scott Walker became the second GOP presidential candidate to drop out of the race for the 2016 presidential nomination.

He suspended his campaign amidst lots of funding issues and a major slide in the polls. Blame has been put on different areas, including Walker’s staff, strategy and lack of fundraising. At the end of the day, Walker’s campaign was no longer organized or had the resources to continue running.

Walker’s departure only narrows the Republican field down to 15 candidates and he was polling at less than 1 percent when he decided to suspend his campaign, so his departure will not have immediate effects on the face of the GOP race. But nonetheless, Walker’s departure could signal the start of an important trend of narrowing down the GOP field to a manageable size.

In his speech announcing his departure, Walker encouraged other Republican candidates polling low down the list to drop out as well so that “the voters can focus on a limited number of candidates who can offer a positive, conservative alternative to the current front-runner,” Donald Trump.

I could not agree with Walker’s words more. Trump’s lead must come in part from the fact that he is the loudest and most dominate personality in the Republican field, which is enough to attract support to be the frontrunner at this stage of the race. There are so many candidates competing for attention that it is hard to even keep track of who they all are. With Walker gone and others at the back of the pack hopefully soon to follow, the race can get down to focusing on a few leaders and hopefully sort out who the real contenders are.

For now the sure thing is that Walker is out. What is unclear is who will be next to follow, and can anyone who remains overtake Trump in the Republican polls?
