Can AAP Replace The 'Crumbling' Congress?

As Rahul Gandhi leads a Bharat Jodo Yatra in hopes of reviving the Congress, his party suffered another massive blow as most of their Goa MLAs defected and joined the BJP. This setback comes at a time when elections in Gujarat are also approaching, and the AAP is aggressively campaigning in the state where the Congress has been the main opposition. But is that now under threat? Arvind Kejriwal has even declared that the Congress is finished. But is it? And is Rahul Gandhi's yatra unable to unite his own party?
