With presumptive Republican nominee, Donald Trump, is set to be

the party’s official nominee, all focus is now shifted on who Trump will pick as his Vice-presidential candidate to run along with him on the same ticket. Donald Trump is now getting into the general election mode and is working over finalizing the name of his co-runner. 

He said he has narrowed down his list of potential running mates to “five or six” in an interview to Associated Press.   

The potential nominees for the post include Iowa Senator Joni Ernst, Florida Senator Marco Rubio and New Jersey Governor Chris Christie, all republicans. In an interview to Fox news on Tuesday night, Trump said he was also considering former Arizona governor Jan Brewer and Oklahoma governor Mary Fallin.

Recently during an interview to Associated Press Trump said “there is no need for another businessman on the Republican ticket and he wants a running mate who can help him pass legislation”.

Till now the best bet is former House speaker Newt Gingrich according to multiple people familiar with discussion. Trump has been asking confidants for inputs on Gingrich as a potential pick.

There is a strong rationale for Gingrich, said Rick Tyler, who was an aide to the lawmaker for 12 years in Congress. He has substantive policy-driven views and knows the world, Tyler said.

Gingrich’s presence may comfort conservatives who say Trump’s campaign has been light on policy proposals.

Gingrich is a historian by training, and holds a doctorate in European history. He is also known for his intellectual curiosity. During his term in Congress, he worked in policy, military affairs and security intelligence, and has a resume of accomplishments.

Trump said that he would reserve his vice-presidential decision till the Party’s National Convention in July.

The primary season is nearing end and the race is now moving towards fall campaigning. The speculation market is high on who will be the vice-presidential candidate. But probably the clouds will only get clear after the Party’s National Convention in the month of July.
