Rand Paul becomes 2nd Republican to enter US presidential race

Conservative US Senator Rand Paul announced today that he is running for his party's nomination for the 2016 presidential race, making him the second major Republican to join the contest.
"I am running for president to return our country to the principles of liberty and limited government," Paul said on his campaign website.
Paul, a conservative libertarian who was elected to the Senate in 2010 with strong support from the Tea Party movement, was expected to make a more formal announcement later in the day.
He summoned supporters and reporters to a speech at 1600 GMT in Louisville, Kentucky, where he has served as senator since January 2011.

Paul follows Texan Ted Cruz, who launched his candidacy two weeks ago with an appeal to religious right, among others.
Jeb Bush, brother of former president George W. Bush, leads in opinion polls for the primary elections, although he has yet to officially announce his candidacy.

On the Democratic side, Hillary Clinton has a team and campaign machine in place, suggesting she will announce in the coming weeks.
In recent days, Paul's team has left little doubt as to his presidential ambitions. A video released recently and hinting at a campaign slogan said: "One leader will stand up to defeat the Washington machine and unleash the American dream."

It was by defying the Republican "establishment" that Paul, now 52, launched his political career in 2009. This was at the start of the anti-tax and small-government movement that would come to exercise a powerful influence within the Republican Party and come to be known as the Tea Party.
And it is by billing himself as a different kind of Republican leader that Paul will look both to rally ultra-conservatives during the primaries and then broaden the base of his party among young people, independents and minorities. It will be a true high wire act.
His father Ron Paul was a libertarian candidate for the presidency -- conservative on economic issues but liberal on social issues.

Rand Paul prefers the term "libertarian conservative" to describe himself, or a "constitutional conservative," taking care to break with libertarian positions considered too strict or even marginal.
He has pushed against the surveillance programs of the National Security Agency and has promoted criminal justice reform to end mandatory jail term minimums, endearing himself with libertarians.
On foreign policy, he has long been in favour of US disengagement, going as far as proposing an end to all US foreign aid.
