Haley, 42, is widely expected to be re-elected for the position which she has held successfully for over three years now, but the entry of Tom Ervin might not make her re-election as smoother as it would have been earlier.
State Senator Vincent Sheheen is challenging Republican Haley, the youngest governor in the US, from the Democratic Party.
Immediately after announcing his governorship bid, Ervin, 62, has launched a scathing attack on Haley, who is not only the first women and non-white governor of the state, but also the first Indian-American women governor.
"Although Haley likes to tout jobs, she has missed the mark in failing to recognise the value of protecting our natural resources. Our state's public beaches and pristine lakes promote tourism. Our rich farmland and forests provide opportunities to grow jobs responsibly," Ervin said.

According to CNN, many see Ervin as a spoiler in the campaign.
"Ervin's audacious, last-minute entry into the race has been met with eye-rolls by Republicans. A popular rumor in Columbia is that his candidacy is little more than a shadow campaign aided by trial attorneys who have long clashed with the pro-business governor and want a spoiler in the race.
"Haley defeated Sheheen by just four points when they first squared off in the 2010 race," the news channel said.
Some Democrats are hopeful that Ervin, and his money, will help them open up a two-front war against Haley on the campaign trail, while siphoning Republican-leaning voters away from the incumbent, it said.
"Governor Haley is focused on the legislative session, passing historic education and ethics reforms and keeping the fantastic economic and jobs momentum going. And we look forward to running against two liberal trial lawyers who support Obamacare instead of just one," Godfrey said.
