It's difficult to predict political outcomes with certainty, but if the BJP is gaining momentum or is favored to win in an upcoming election, it could be due to various factors such as their policies, campaign strategies, public sentiment, and the political landscape at that time. However, outcomes can always surprise, so it's essential to consider all factors and wait for the actual results. 

The Congress versus BJP contest in the 2024 elections could be influenced by several factors. Both parties will likely focus on their respective agendas, campaign strategies, and leadership to garner support from voters.

The BJP may highlight its governance record, development initiatives, and national security policies as key achievements, while also emphasizing its commitment to Hindutva ideology. They may also focus on projecting a strong leadership image, potentially led by Narendra Modi.

On the other hand, the Congress party may emphasize issues such as social justice, economic reforms, and inclusivity. They might critique the BJP's policies on various fronts, highlighting areas where they believe the ruling party has failed to deliver on its promises.

Ultimately, the outcome of the 2024 elections will depend on a multitude of factors including voter sentiment, regional dynamics, economic conditions, and campaign strategies deployed by both parties.
