Sucharita was elected as an MLA from Prathipadu segment for the first time in 2009 on Congress ticket. She was inducted into the Congress by the late Dr. Y S Rajashekara Reddy (YSR) after he spotted her during his historic ‘padayatra’ in 2003. Groomed by YSR during his tenure as chief minister of undivided Andhra Pradesh, Sucharita's rise to the cabinet rank began in 2006 when she won the Zilla Parishad Territorial Constituencies (ZPTC) election from Phirangipuram in Guntur as a Congress candidate. She served for two years as ZPTC member.

In 2009, YSR allotted her the party ticket for Prathipadu Assembly Constituency in Guntur district from where she won comfortably. After YSR's death in September 2009, she swore allegiance to Y S Jagan Mohan Reddy and resigned from Congress when Jagan launched YSRCP in March 2011. She again won from the seat on a YSRCP ticket in the by-elections held in May 2012.

Despite conceding her seat to the TDP in 2014, Sucharita's loyalty to the YSR family was rewarded with Jagan again allotting her the YSRCP ticket in the 2019 assembly elections.^[3] She defeated two heavyweights — former minister D Manikya Vara Prasad of the TDP and former TDP minister Ravela Kishore Babu, who joined Jana Sena Party.
