The process for selection of candidates, as devised by party vice-president Rahul Gandhi, "is underway and it is right now difficult to disclose any date" for announcing the list, Maken said, after inaugurating a renovated communication centre here.
All 4,000 willing candidates for the December 1 elections have been interviewed and the AICC screening committee have met twice in Delhi to decide on the matter, he said, adding "we will sit in Delhi again today itself".
As many as 4,000 people are vying for tickets for 200 assembly seats
Asked about fielding tainted leaders in the Assembly polls, the Congress leader said, "Rahulji wants winnable candidates with good and clean image."
"Tainted candidates' authenticity and truthfulness would be verified. Merits of aspiring candidates would be considered first," Maken said, with Chief Minister Ashok Gehlot and PCC president Chandrabhan by his side.
Asked whether the party would consider giving tickets to Independents supporting the Gehlot government, Maken said, "There is no policy decision on it".
"There is bright prospect of Congress coming to power again in Rajasthan", despite the delay in candidate selection, he said, adding Rahulji and Soniaji's rallies held in parts of Rajasthan in the past two months have generated great enthusiasm among supporters.
Anticipating a larger role to be played by social media in coming elections, Maken said, "I totally agree with the Election Commission that social media should be monitored as poll campaigns have started coming on Facebook and Twitter".
Maken said his party has modernised its communication centres in all state headquarters to popularise party's achievements through social media.
All state headquarters will also be linked with AICC through "video-conference" in near future, he said.
Later Maken addressed party leaders and workers on communication skills and designs at the party office.
