Nitish Kumar came armed not just with a quiver full of political arrows to aim at rival Narendra Modi today, but also admission cards from the latter's Sunday rally in Patna.During his sustained diatribe against the BJP's presumptive prime minister at his party's convention in Rajgir, the Bihar chief minister held one of the cards up and said, "See these were made in China. They talk of Swadeshi (Made in India), but now for every small event will they get things made in China?Mr Kumar then fished out another laminated ID card from his pocket and held it up. "These are ours. Made in Bihar, in India," he said.The Janata Dal United leader advised the people of his state not to be swayed by the BJP's claim that a "Modi wave" is sweeping the country. "Do not believe poll surveys. Do not be afraid. It's a public relations exercise. Treat it as entertainment."The "small event" that Mr Kumar dismissed was a big show of strength by the BJP at the Gandhi Maidan in Patna on Sunday. In a very long address, just after a string of blasts that killed six people, Mr Modi tore into Mr Kumar and his administration. Mr Kumar said he would respond later.Today, two days, later he used his party forum to strike back predicting that Mr Modi's "Red Fort dream, will remain a dream."

He also refuted the BJP's allegations of "gross criminal negligence" by his government in its poor security arrangements for Mr Modi's public gathering at Gandhi Maidan, where six of the seven blasts in Patna took on place on Sunday.The JD(U) and the BJP were partners till June this year when Mr Kumar broke the 17-year alliance over Mr Modi's elevation in his party.
